SPECIFICATION forming part of Letters Patent No. 604,84A, dated May 31, 1.8598.- Application filed January 12, 1898. Serial No. 666,470. (No model.)

To a-ZZ Iii/mm, it "my concern:

Be it known that I, GEORGE I. ROBERTS, a citizen of the United States, residing at New Rochelle, in the county of \Vestchester and State of New York, have invented certain new and useful Improvements in SteameSeparators for the Removal of Water, Grease, and

Foreign Matter or Materials, of which the,

following is a specification, reference being had to the accompanying drawings.

My invention relates to the application of certain additional improvements to the construction, arrangement, and combination illustrated and described in the patent granted to me under date of August 3, 1897, No. 587,560.

The object of these my present improvements is to increase the eiiiciency, improve the construction, character, scope, and operation of the apparatus and its results, more especially to provide against the possibility of the refuse grease, oil, foreign matters or materials passing in any direction other than through their proper and designated channels or paths of exit; also, to provide for a ready cleansing of all the parts or portions likely to become dirty.

Myimprovcments consist in the special construction, arrangement, and combination of the several parts or portions comprising the improved apparatus, as may be hereinafter described,illustrated, and claimed.

Referring to the accompanying drawings, Figure 1 represents a vertical longitudinal section of my improved apparatus. Fig. 2 represents a transverse section of the same on line 03a: of Fig. 1,10oking to the right,

. showing both chain and rope in battle-arches.

Fig. 3' represents a transverse section of the same on line y y of Fig. 1, looking also to the right.

In theseveral figures, 2 designates the main shell, inclosing the several parts or portions comprising the separating apparatus. This shell may of course be of any desired shape, form, or configuration, but for strength and lightness it is preferably made cylindrical.

Li designates an upper or steam-receiving compartment into which all surplus, exhaust, unused, or ref use steam or vapor is delivered for treatment, and 5 designates a lower or dripn'cceiving compartment for the reception 10 is carried down to within of extraneous oil,'water, grease, foreign material or matter sifted, separated, or taken from the steam.

6 designates a pair of supporting-strips, preferably of angle-iron, fastened along the central longitudinal sides of the main shell for the purpose of supporting the removable chain or rope battle frames 7, already described inPatent No. 587,560, and for likewise supporting a removable horizontally-laid partition-plate 8, resting upon said strips directly beneath the steam-receiving opening 9 and extending to the baffle-frames, leaving an inlet-opening to the lower driprccei\-'ing chamber 5. A

10 designates a fixed partition-apron extending from the right-hand upper end a short distance below the steam discharge opening 11 downwardly, as seen in Fig. 1, past the bottom of battle-frames to and well into the drip-receivingcompartment. A partition-dam 12 is provided over which all surplus lighter inatter-or materials flow into the oil or grease compartment 13.

14 designates an upwardlyprojecting discharge or blow-off nozzle. Partition-apron. a short distance of the bottom of the main shell, and all water is forced to-pass beneath it. The upwardly projecting discharge or blow oii nozzle is carried up to a height or elevation above the hottom of partition-apron 12 to prevent in the emptying of the tank any possibility of theoil, grease, or lighter matter or materials getting below or past the bottom. of partition-apron 12 and passing out with Water when the level of the water is raised.

15 designates an npwardly-projecting retarding-dam located to hinder and. prohibit all heavier matter passing to the final delivcry-compartment. It is preferably inclined toward, although it may be set vertically to Within a short distance of, the partition-apron 10 to provide a reduced area of passage for the water-into the next compartment. A final partition-da1n 16 is providccbover which all the Waterilows or falls into'the exit-compartment 17. Partition-apron 10 and retarding-dam 15 inclose a compartment 13, into which filtering or clarifyin g material is preferably packed in case there is considerable impurities in suspension in the drip-water. A settling men t.

compartment 19 is formed by the retardingdam 15 and the final. pi1|1'titi0r(12tl'.. 16, into which all water passes before rising to overflow into exit-compartment 17,

lhe partitiondam 1 5 for water and that for oil are both carried to the same overiiow height, and the oil, grease, &c., being of less specific gravity than water, floats above waterdevel and necessarily and readilyoverfiows to the oil-receiving com partment 13, whence'it is drawn off or discharged.

The retaining-partition should not be carried to the same height as overflow-dams 12 and 16, about one-half the height being preferable and advisable.

In the present device the perforated horizontal partition beneath the chain bafiies is done away with. The chain bafiies, resting upon the strips 6, are allowed and caused to drip directly into the lower compartment 5, as illustrated by drip-lines in Fig. 1, the clear ance-spa-ces between the bafiie-frames being sufficient for all drip purposes.

in the operation of this device the steam to be cleansed is admitted through receivingnozzle 9, meets its first resistance in partitionplate 8, whence it reacts. and passes through the chain bafliers '7, where it is freed of its foreign matterwater, oil, &c.-passing into the discharge end'of upper chamber 3 and out of discharge-nozzle ll. The foreign mat- 'ter--grease,water, oil,&c.is sifted from the steam and drips from the chain baiiles 7 into the lower drip receiving compartment 5, whence the lighter materials or matter overflow the partition-dam 12 into oil-discharge compartment 13. The water, being heavier, remains in the drip-receiving compartment 5, passes downward under partition-apron 10, over the retarding-dam l5, and finally over partitiondam 16 into exit-compartment 17 for withdrawal.

Before commencing to use the device suil'icient water should be entered into the lower drip-receiving chamber to cover thoroughly the bottom edge of the partition-apron 10 and the discharge or blow-off nozzle 14,so.that no drip grease, oil, or foreign matter or material of light weight and specific gravity shall reach or pass under the lower edge of the partitionapron 10.

To clean the apparatus, cover 20 of the upper compartment is removed, partition-plate E. a nd bathe-frames 7 are withdrawn, and free access is at once attained for the cleansing of every portion likely to get dirty. The filtering or clarifying material may be removed from beneath the lower edge of partitionapron 1t).

In the drawings sixteen of tho chain-battle 'frames'iiti'c shown. This number may be in- 'or decreased, according to requirend the inlet or opening to drip-compartment {a reduced in' area by extending either-the removable partition 8 or-the partition-apron 10, or both, to reach the baffles, according to their preferred location.

naturally 23 designates a float automatically operating valve 2t to eifect the emptying of watercompartment 17 by gravity, pump, or other well known means. The same automatic method is preferably used for emptying compartment 13 as well, primarily to save oil and grease for clarifying and future use, and, sec-.

ondly, to so control the oil or grease level that it shall not flow back toward compartment 5, and thus mar the efficiency of the separator as a whole. In such case outlets 21 or 26, or both, may be used for the purpose. These same outlets 21 and 26 may be used as ordinary blow-outlets for discharging the oil or-grease by hand, according to the level shown in the gage-glass 28, the oil or grease being saved or thrown away as desired. With outlet 26 used as a surface-dischargepartition-dam 12 may be omitted, if desired, and lower drip-compartment 5 extended to the admission end of the main shell.

22 designates the discharge or blow-off pipes and valves for cleansing the several compartments of any accumulated foul or undesired waste matter or material.
